摘  要这些年来，我国经济发展十分迅速，越来越多的人向城市进行迁移。城市化趋势愈发明显，室内人员集中场所增多，因此，火灾发生频率和规模有增长趋势，这种现象需要人们引起足够的重视，及时消除隐患，确保消防安全。目前，火灾自动检测报警系统在很多地方已经成为必要的装置，起到了重要的安全保障的作用，但是在实际应用中，也出现了许多的问题，市场上现部分产品存在功能单一，可靠性、稳定性不高，部分产品仅仅针对其中某一个方面进行探测，易出现错报、漏报的情况。69241

本设计研究目的在于提出一种利用LabVIEW综合管理平台运行的火灾探测报警方案，通过多个传感器节点，采集多个不同的火灾参数，通过无线传感器网络ZigBee进行数据的传输，再利用上位机数据综合管理平台LabVIEW进行参数值的判断，对火灾的发生进行及时、准确的预警和报警。本设计系统打破传统有线形式的传播，利用无线通信技术将无线火灾报警技术向智能化、网络化的方向发展；并且本设计采用多种传感器，对于不同参数进行检测，提高了火灾探测的灵敏度；利用数据综合管理平台对于实时数据进行监控并且保存数据，将火灾报警技术向着低误报率、高可靠性方向发展。

The design of wireless fire alarm system based on LabVIEW

Abstract

Over the years, China's economy developed rapidly, More and more people are moving to cities. Urbanization trend is becoming increasingly apparent, place increased focus person in the room, so the fire frequency and scale of growth trend, this phenomenon requires people to attract enough attention promptly eliminate hidden dangers, to ensure fire safety. Currently, automatic fire detection and alarm systems in many places has become a necessary means to play an important role in security, but in practice, there have been many problems, some of the products now exist single function, reliability on the market, stability is not high, some of the products for which detect only one aspect, prone to false statements and omissions of the situation.

    The design study aims to propose a use of fire detection and alarm management platform LabVIEW program run by a plurality of sensor nodes, collecting a number of different fire parameters for data transmission via wireless sensor networks ZigBee, re-use PC data integration management platform LabVIEW judgment parameter values for fire timely and accurate warnings and alarms. The system is designed to break the traditional forms of wired communication, using wireless communication technology to the intelligent, network-oriented direction wireless fire alarm technology; and this design uses a variety of sensors for detecting different parameters, improved fire detection sensitivity; using data integrated management platform for real-time data monitoring and saving data, the fire alarm technology towards a low false alarm rate, high reliability direction.
